Subject: [PATCH] Use newer `language-` class name prefix

This change makes it partly possible to use Jekyll+RedCarpet+Prism.js without using a plugin.

Another change will respect Jekyll's `pygments` configuration option and not render the code block using Pygments. Together, these two changes allow using prism.js with Jekyll out of the box.
